Electrical problem
2000 Saab 9-5 4 cyl Two Wheel Drive Automatic

Sometimes car won't start, when engine warm. If left for a while (increasingly longer period - now 45mins) will start again without difficulty. This doesn't occur for some time and then reappears again.

Sometimes car won't start,

Next time it refuses to start don't wait -check if its a fuel or spark problem-do below

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
